For the contractor POMGRAD INŽENJERING d.o.o. from Split, during the construction of the liquefied natural gas terminal (LNG terminal) near Omišalj on the island of Krk, during the execution of the works we carried out a series of control surveys in the area of three shoals that needed to be deepened, as well as final shots of the completed state of the shoals and the terminal pier. Based on our studies for the terminal and the shoal area, we have obtained the Decisions of the Croatian Hydrographic Institute by which this maritime infrastructure can be entered into the official maritime charts of HHI and obtain a use permit.
